The electroencephalogram (EEG) is a test that detect electrical activity in the mind using tiny, metal disks (electrodes) attached to the skin. The brain cells interact via electrical impulses and are activated always, even when you are un conscious. the process shows up as wavy lines on the EEG signal. Within the EEG even metal disks (electrodes) are attached to the skin . in the high-density EEG, presented here, these electrodes are closely separated together. These electrodes are linked to the EEG Device with wires. Some people have the elastic jacket fitted with electrodes , instead of having the material used to their Scalps
Nerve Conduction Velocity Test (NCV)
Nerve Conduction velocity test (NCV) tests measures communication intensity and velocity along specific large motor sensory nerves. they may discover hearts and hearts cases involved and whether symptoms are caused by degradation of the myelin sheath or the axon. During the experiment, The probe electrically stimulates the nerve fiber, which reacts by generating its own electrical pulse. The electrode put further along the nerve's path measures the rates of communication transmission along the axon . Slow communication rates tend to suggest damages to the myelin sheath , while the decrease in the intensity of impulses in regular speeds is a sign of axonal degradation . inability to elicit signals may present serious issues
Electromyography (EMG) is the kind of Electromyography experiment that is used to analyze heart and muscle function . Its usually performed by the physicist or specialist with special preparation for the process. The EMG heart test will be provide the physician with particular knowledge about the magnitude of nerve and /or muscle loss and may also determine the correct position of accident and give some reason whether the damage is reversible . some people ask" is the EMG Experiment uncomfortable? " There are really two components to EMG examination and both may result in some suffering , but they are normally easily tolerated without any demand for pain therapy. in most cases , the physician can do both components , but in some places , just one or the other may be made.
